The Path to -to-Bottle PET Made Easier With Our CleanFlake™ Portfolio. material advances allow brand owners to improve recyclability

Advances by Avery Dennison have leveled the playing field for PET recyclability and shelf-impact. Traditionally there has been a trade-off between the two; however, the CleanFlake™ Portfolio is designed specifically for the PET ( terephthalate) recycling stream. PET is a popular plastic package for food and non-food products because of its strength, thermo-stability and transparency. Bottle-to-bottle recycling reduces landfills, enables up-cycling into food-grade rPET and capitalizes on the renewable energy in a PET bottle. Brand owners, packaging designers, raw material suppliers, , retailers, consumers and management companies collectively impact sustainability. While the overall goal is to make it easier to recover more materials, brand owners look beyond package design. They recognize sustainability can offer a significant point of differentiation as retailers’ demands and consumer awareness about the environment and natural resources carry increasing influence towards the brands that are put on store shelves and in shopping . “NAPCOR applauds Avery Dennison and its customers for addressing a critical impediment to the efficient recycling of PET ,” said Mike Schedler, National Association for PET Resources (NAPCOR) Director of Technology. “The popularity of pressure-sensitive and shrink makes it imperative that they be successfully removed as part of the standard PET reclamation process to increase their recyclability. We hope other label manufacturers and brand owners follow Avery Dennison’s lead.”

Promoting Sustainability, Creating Shelf Appeal and Capturing Share Whether it’s a private label or a national brand, consumers will only Pressure-sensitive and shrink labels normally limit PET recyclability spend about 2.5 seconds at the shelf deciding what product to into food-grader PET due to contamination. However, buy. So what influences them the most? Increasingly, it’s brand Avery Dennison has developed a “switchable” pressure-sensitive recognition generated by compelling graphics and curvaceous label adhesive, SR3010, which can be “turned on” or “turned off” containers. These two elements are the primary differentiators for depending upon the environment or external stimuli.

The and the overall quality of post-consumer plastics. formulation of SR3010 is more complex, requiring a switching mechanism and specialized components to turn the adhesive “on” and “off.” But SR3010 isn’t the only way to improve recyclability. Avery Dennison’s CleanFlake™ Roll Fed Shrink Labels are the perfect plug-and-play solutions to increase sustainability and decrease waste. These labels use no adhesive, so they can be separated using two gavimetric processes—the sink float process or air elutration. During the sink float process, the label is cleanly separated from the PET flake in a warm caustic bath. The air elutration process allows air bursts to separate the label from the PET flake according to density. APR-Approved Solution Our CleanFlake™ Portfolio is a bottle-to-bottle recycling solution that offers a roll-fed shrink and two pressure-sensitive label options—clear and white facestocks. Both film stocks have a density of less than 1.0 and have passed the Association of Postconsumer Plastic Recyclers (APR) recycle protocol for PET containers with plastic pressure-sensitive labels. Our 100-percent recyclable clear and white facestocks, and clear 40 and 50 MDO shrink films deliver the same quality, clarity and performance of traditional pressure-sensitive and roll fed shrink films. Compatible with flexo, gravure and offset techniques, brand owners have a simple, yet immediate, label replacement strategy that makes their PET product packaging recyclable and reusable safely. Increasing PET Recycling According to a market study by Smithers Pira, the global consumption of PET packaging will reach an estimated 19.1 million tons by 2017. PET consumption will continue to rise as brand owners look for creative ways to bring products to market. However, driving the need for sustainability is stronger legislative and resource protection programs. As such, the potential exists that a full reclamation infrastructure will not yet be established to effectively process these materials. It is clear that reclamation facilities are vital to the industry. The need for more facilities is obvious, but those that are online today must be effective at sorting and processing. To make bottle-to-bottle recycling a workable venture, residual contamination of the PET recycling process due to label materials must be resolved. These facilities purchase post-consumer , sort and clean them to produce a viable flake for remanufacturing. The contaminated recycled PET can lead to color issues, loss of intrinsic viscosity, loss of clarity, extruder drip and black specs. Unfortunately, the end result is the contaminated materials are only suitable for down-cycling into lower-grade products. A greater reinvestment in technology is needed that makes it possible to up-cycle the regrind into something of greater value or use, thereby reducing waste and the need for virgin material. Improving PET Quality Contamination in the PET recycling process has been a long-standing issue for everyone involved in recyclable packaging. All plastic label options, from pressure-sensitive to shrink sleeve, impact PET packaging design and recycling. The APR recommends the use of plastic labels with a specific gravity of less than 1.0. These are preferred because they are easily removed in conventional water-based density separation systems. APR recommends avoiding label systems that sink in water since the substrate, inks, decoration, and the top layer are contaminants in recycled PET flake. Once separated, the PET bottles and their labels move onto grinding. Labels that stay on through the granulation and elutriation process can be separated from PET flakes for best quality. At drying temperatures from 165 degrees centigrade or lower, label materials tend to clump and stick in dryers, requiring costly and unscheduled maintenance. It is also critical that the label be fully removed from the flake for subsequent processing. Finally, care must be taken to select caustic-resistant ink systems to avoid bleeding into the wash by being processed. A Sustainable PET Recyclable Solution Finding a solution that can maintain the integrity of the PET recycling in the total number of PET bottles and available for recycling. stream is vital to the sustainable practices for brand owners and So, while the recycling rate represents an ongoing commitment converters, the goal of which is to reduce, and recycle. to recycling, the need to recycle more is clear. The challenge for According to the APR and the American Chemistry Council (ACC), packaging decision makers is to leverage this commitment by the PET container-recycling rate has more than doubled within designing PET packaging in a way that enhances recyclability, the past 8 years—reaching above 30.8 percent in 2012. However, especially for closed-loop, bottle-to-bottle operations. despite the increase, there was still a 4 percent decrease by weight

Brand owners are increasingly aware of the global signifi cance of maintaining the integrity of the PET recycling stream. To address the issue, reclaimers encourage the use of plastic label materials with a specifi c gravity of less than 1.0, as well as attributes like perforations on full-wrap shrink labels that aid in their removal and improve the overall recycling process. Another option for a long-term solution is using a label that fl oats when processed, is compatible with the existing label stream and PET recycling infrastructure, and is consistent with the Design for Recycling Guidelines established by the APR.
